easily constructed. We examine the performance of three high-rate (0.769, 0.889, 0.935)
LDPC codes in image transmission. Simulation results show that LDPC codes are good
coding schemes over fading channels in image communication with lower system

As a class of block codes, LDPC codes with any desired code rate and code length are easily constructed. We examine the performance of three high-rate (0.769, 0.889, 0.935) LDPC codes in image transmission. Simulation results show that LDPC codes are good coding schemes over fading channels in image communication with lower system complexity. The distorted images can be recovered by using the three high-rate LDPC codes at SNR of 10 dB, 11.5 dB and 14 dB respectively. These high-rate codes can achieve relatively higher bandwidth efficiency than the low-rate codes can. Moreover, we discovered that the code rate has more influence on the performance than the code length does.
